I use conditional plug 1.8.10.
No field reset value is enabled.
I tested several adjustments. There is only a problem, when a fild with conditional is published in the registration. I.e.:
Publishing of "Country" is no problem.
Publishing of "State", which depend on the selection in "Country", cause the problem. The Plugin in general should be ok.
I unpublished the conditional fields on the registration site ("State"), the user have to choose this fields after login. It works for me now, but I´m looking forward to use the conditional fields on the registration site.
